I hear a bell ringing in the distance. This indicates that the problem is not related to the size of the data, but its content. If the data-link path wasn't 8-bit clean (say, the SCO terminal device was doing cr->cr-lf translations on the TCP packets for example), is it possible that tcpdump shows the incoming (corrupted) packets coming up through bpf but the TCP code discards them because the checksum is invalid? This would explain why the FreeBSD box apparently "sees" the incoming packet, but the TCP stack doesn't respond to it.
